ES05
There was one (1) Action
Level exceedance of 24-hour TSP recorded at Location AM2. Investigation result revealed that the Contractor has implemented dust mitigation
measures to control the dust generated under the Project. It was concluded that the exceedance was related to other dust source such as
frequent road traffic apart from the project and work area owned by other
project without proper maintenance site exit along Lin Ma Hang Road and unlikely due to the works under Contract works.
ES06
A total of eleven
(11) Limit Level
exceedances were recorded during water
quality monitoring. Investigation for cause of water quality exceedances have conducted by
ET. Investigation report revealed that the exceedances recorded at WM2A(a) on 2 November 2018 and WM3x on 17 November 2018 was
not caused by the works under the Project. Investigation report revealed that the
exceedance recorded at WM3x on 10 November was caused to the isolated incident of burst water
pipe which related to the works under Contract 6. Furthermore, the investigation for exceedances recorded at WM2A(a) on 26, 27 and 28 November 2018 are still underway by
ET and the investigation result will be presented in next Monthly EM&A
Report.
Environmental
Complaint
ES07
In this Reporting
Period, one (1) documented environmental
complaint was received from EPD on 19 November 2018 concerning
about the dust impact generated from the demolition work for a temporary bridge
near Kau Lung Hang with insufficient dust control
measures. Remedial action was
undertaken by the Contractor immediately and satisfied by EPD. Follow up investigation
was conducted by ET and it was observed that the situation was improved. Investigation
report for the complaint is underway by ET.

2018. No non-compliance was noted during the site inspection.
Future Key Issues
ES16
During dry season, special attention
should be paid on the potential construction dust impact since most of the construction sites are adjacent
to villages. The Contractor should fully implement the construction dust
mitigation measures as appropriately.
ES17
Preventive measures for muddy water or other water
pollutants from site surface flow to local stream such as Kong Yiu Channel, Ma Wat Channel, Ping
Yuen River, Kwan Tei River or public area should be
properly maintained. The Contractors should paid special attention on water
quality mitigation measures and fully implement according ISEMM of the EM&A
Manual, in particular for working areas near Ma Wat Channel and Ping Yuen
River.
ES18
In addition, all
effluent discharge shall be ensure to fulfill Technical Memorandum of Effluent
Discharged into Drainage and Sewerage Systems, inland and Coastal Waters
criteria or discharge permits stipulation.
ES19
Construction noise would be a key
environmental issue during construction work of the Project. Noise mitigation measures such as using
quiet plants should be implemented in accordance with the EM&A requirement.
ES20
Since most of construction sites under the
Project are located adjacent to villages, the Contractors should fully
implement air quality mitigation measures to reduce construction dust emission.
